To all whom t may ronoem Be it known that I, CLARENCE A. Goo SHALK, a citizen of the Unitedttesgresid ing at Ardmore, in the county ot Montments in Locks for Spare Tires, of which the following 1s a speeiieation.A

.My invention relates to means for lockingv a nut in place upon a bolt or pin, and which may be put to a Wide variety of uses. It. consists of a nut, o. casing united thereto so as to turn therewith, and key-operated lock mechanism so arranged and operating that the easingY may be looked to a `tired or rigid part of the machinery or eppferatus in conneotion with which the nut may be used in such manner as to prevent the turning or removal of the nut except by the use of the proper key which will relensegthe nut from its locked condition. That embodiment of the invention herein presented relates ton lock for preventing theft of spare tires from motor fvehicles. and with that fspeeiiie form of my invention in contemplation one of tho objects thereof is to provide a lock for o n spare tire having a. minimum number of parts and being simple in manufacture and capable otproduetion` at small expense.

Another object of the invention is to provide a spare tire loeli; for automobiles aryrangedso that noise arising from rattling of parts together under 'onditions of vibration is eliminated.

further object of the invention is to provide aioclr for a spare tire Iarranged to cooperate with the usual form of tire ear rier wherein the lock 'also serves as a nut operating against Wedge fitting to rigidly -secure the tire in position upon the tire ear.- rier with detachable means for preventing the unsorevving of the not 'until the look tumblers ere moved by efkey operating in the look.

A'furthjer object or the invention is to provide a look nut for attachment to all standard forms of spare tire carriers for; preventing the/removal of aJ tire from tite carrier except bythe use of a special cooperating key forv the lock. 'y

Another object of the invention is to provide e spare-tire carrier with meansi for retainingothe. tire thereon .having suiiicient leverage-whereby the screvvl vmeans may be operantosinmanuelly without the necessity of o special Wrench or tool normally required in securingr a My' stood4 by reference to the accompanying drawings, in which:

Heretofore in the art it hasheen usual to lock a spare tire upon a ,tire carrier by utilizing o padlock looping into vva bracket on thecarrier frame and a Wedge'sh'aped member which is secured against the rim of the spare tire by a, nut screwed over a bolt extending from. the carrier. These/.forms of tire locks have inherently involved loose Aports which rattle and knocktogether under conditions of vibration as the automobile :travels over the road. Such forms of locks to-serewthe retaining nut upon the bolt extending from the tire carrier, and finally the padlock vmust be applied.

My invention contemplates a construction.

of lock which serves both as a 'retainingnut y reqi'iire theta. special wrench be used, first rim 2 which issupport'ed upon the tire car- 'y rior B mountedupon the rear or upon a running board of a vehicle 4. Thetire carrierln- .merely with the fingers Without t e cludes a bracket fitting secured to the tire carrier as indicated at 6. An extended screw threaded bolt 7 projects from the bracket fitting 5. A wedge shaped member or holding piece 8 is arranged with cam faces bearing against the tire carrier 3 and thetire run 2, forcing the tire upon the carrier when the screw threaded portion 9 of lock 10 is rotated to take up the threads on the bolt 7. The body` portion ofl the lock 10 is suiiicientl extended from the center line of bolt 7 so t at thepnut 9 ma be screwed over the threads of the bolt y vrotatin the lock use of a tool usually required wit A wrench may .be used on the outside of the body at lock 10 to tightly secure the nut portiony 9: on the' bolt 7. The body portion 10 is rotated to a vertical position, then a pin 12 inserted through special wrench or spare tire carriers.

The pin 12 is provided with -an annular neck 18 arranged to cooperate with tumblers interior which the pin is rigidly u secured in the lock. The nu't portion 9 canapertures 14 and 15.

not be rotated with the pin in the locked position. The lock 10`is operated by a key 19. .A so

inserted in key hole l20.

When the tire is to be removed from the Vtire carrier the key 19 is turned in the lock 10 permitting pin 12 to bemanuallywithdrawn bygraspingfthe hea/d 21 which forms a finger grip, and horizontally withdrawing the pin 12 from lthe socket 16 and free of The nut ortion 9 may now be unscrewedfrom the olt 7 by either rotating the lock 10 with the fingers -or utilizing a wrench whereby the spare tire is readily removed from the carrier.

It will be observed that the pin 12 is offset to a considerable distancefrom the axis of the bolt 7, and is parallel therewith, and that it sets in apertures, 14 and 15, which are all found in the standard equipment of tire car- I rier which I have illustrated in the drawing,

thus making it unnecessary that any alteration be made to such standard equipment. The carrier 3, the bracket 5, the bolt 7, and the holding piece 8 are all utilized exactly as found upon thousands of cars as rijow lequipped with spare tire carriers. Lam aware that it has been proposed to lok a nut upon a bolt'fcorresppnding with that shown at 7 in the accompanying drawings by means of lock mechanism supported in a casing carried by the nut that engages the "bolt, a moving part of which lock enters a longitudinal kerf or channel formed in the bolt, and hence make no claim to such an arrangement; but there are distinct advantages in my invention over and above an arrangement such as just indicated. Such an use of e.' epe- /ter found in many other places 'threaded end of a h tempt to remove the nut in an unauthorized manner. s

meneer cially prepared threaded bolt, one having a longitudinal channel to be engaged by the moving part of the lock, but my lock is adapted to be applied directly to the threaded bolt found upon the car, or for that matwhere the bolt is exposed to receive a nut. Another advantage incident to my construction is that the pin 12 that prevents the turning'of the nut and which locks it to a permanent or fixed art of the apparatus is offset at a considera le distance from the axis of the bolt, making it increasingly dif- [icult to force-or break the lock in an at- While I have described my invention in a certain specific embodiment, it is to be understood that I intend no limitations upon the invention other than are imposed by the scope of the appended claims.

' The use to which the invention is put as described in this specification is illustrative of its specific application to a particular industry. However, the nut,y adapted to be locked in position upon a pin or bolt by a keyoperated lock that unites the nut with a fixed or rigid part of the apparatus ofiset from the bolt in connection with which the nut is used, is adapted for use in a great number of other situations Where nuts are employed for holding parts of machinery or apparatus in place, and where the unauthorized removal of the nut is to be prevented.

What I claim and desire to secure by Letters Patent of the United States is:
